Jeffrey, I hope that you're doing well. And hope that your surgery is a success.
As for the "new" IE, things haven't gone good today. It has crashed multiple times, and I have no choice but to continue using Firefox. I can see once, but at least seven times today? This is unacceptable performance, for a browser that started with no problems, with lots of promise, then goes in reverse.
I could have seen this happening on the first few days, but as time goes, any piece of software should improve, not slide backwards. IE9 still has a long way to go, and as another member stated, "too little, too late". Not enough add ons, way too many ads, and constantly crashing today (on different OS's) is sufficient reason to drop IE9 (and to be fair, any other browser as well). Beta or not.
IE's "glory" days ended with the release of IE8, and there's no reason to expect things to improve, given the success of the alternatives.
I will always maintain that while Bill Gates was in charge of things, he ran a tight ship. He always demanded perfection from his employees, and nothing less. He took it to the competition with everything that he had, remember the "browser wars" of the 90's, he picked apart a leader at that time, Netscape, and disposed of them. He had IE on a huge roll, but now that he's gone, IE is steadily becoming a laughing stock of a browser.
If it were not for the fact that IE ships with Windows, it would sink fast. Windows is the only reason that IE's stock is so high today, not that everyone actually uses it, just as everyone does not use their backup, defrag, disc cleaner, and other products.
XP will probably outlast IE, as far as popularity goes.
